Top panel: CMD of the Hyades sample with the mean polluted isochrone (solid line) and LOWESS fit (dashed line) superposed. Bottom panel: Scatter plot in Δ﹩M_{V}﹩ of the Hyades sample about the LOWESS fit. Superimposed are the differences between the 2 σ isochrones and the mean isochrone (dashed line: +2 σ; dotted line: −2 σ).
